Since the foundation of FBI laboratory's Combined DNA Index System (CODIS) a decade ago, the 13 CODIS STR loci of the system as well as the recently developed Penta D, Penta E, D2S1338 and D19S433 loci have been widely used by kinship testing laboratories worldwide and have played an important role in the field of Kinship Testing and in construction of criminal database. This article systemically analyzed the characteristics of STR loci information and its genomic information analyzed through search of a variety of database including Webof Knowledge, Elsevier and Internet resources. The up-to-date application of the commonly used STR loci in recent years is also reviewed.
